Abstract: Perceived usefulness has been found to be significantly correlated with self-reported current use and selfpredicted future use of information systems.However, Davis (1989) points out that perceived usefulness is a subjective appraisal of system performance, and thus it may lead to under or over estimates of performance.Underestimates of system performance may lead to decreased satisfaction and a refusal to use the system, despite possibilities of objective performance enhancement, while on the other hand overestimates of system performance may lead to increased satisfaction and use of a system, even thought the system is objectively detrimental to performance.In the current study we examine the impact of two types of DSS support, decisional guidance and cognitive feedback, on user estimates of DSS performance and user satisfaction with the DSS.The results of the study show that subjects receiving cognitive feedback were as satisfied with their DSS as subjects receiving decisional guidance, despite having much poorer performance levels.We discuss the implications of these results for the accurate measurement of user perceptions of DSS usefulness.
